NHTSA Complaint #11701023 — 2019 GMC SIERRA 1500

Around June 2025 under normal driving my truck displayed engine oil low which I promptly checked the oil to find that it was in range. The light later went off but I still brought it to the dealership to which they could find no issues. From there over the next month or so the truck developed a low end popping sound on start up and at my next oil change at the dealership in August of 25 I asked them to listen to see if they heard it and could recommend a course of action. They reported not hearing anything. On October 19th I had my family in the truck with me and during normal acceleration the engine had a loud pop sound and lost power. Every warning light came on and I pulled over promptly when safe. I had it towed to the dealership and their initial diagnosis was a failure on cylinder 4 with a suspected failure of either the cam shaft or lifter. Given the poor design of the lifter I didn’t want to go back with the OEM lifter so I had it towed to an aftermarket shop. It is there now and they are in the process of tearing down the engine. After watching a video on YouTube I fear my truck is part of the connecting rod bearing failure under PE25-001. My understanding is there is an official investigation into the trucks outside the initial recall. I wanted to submit this for your review as the truck only had 74,000 miles. Freeman GMC in Grapevine, Tx has performed all the maintenance and should have documentation.
